Description
上記目的を達成するための1つの開示は、
道路のレーンをレーンの一部を示すリンクの接続によりモデル化して示すレーンネットワーク情報が表されている地図データ(34)を記憶する地図記憶部(32)と、
車両の現在位置を決定する位置決定部(41)と、
位置決定部が決定した現在位置に基づいて定まる領域に対する地図データを地図記憶部から読み出す読み出し処理部(42)と、
読み出し処理部が読み出した地図データに基づいて、地図データに対して情報量が多くされた制御用地図データ(35)を作成する制御用地図作成部(43)と、
制御用地図データを、車両の挙動を制御する車両制御装置へ出力する出力部(44)とを備える、地図データ出力装置である。
One disclosure to achieve the above objectives is
A map storage unit (32) that stores map data (34) that represents lane network information that models a road lane by connecting a link that indicates a part of the lane.
Positioning unit (41) that determines the current position of the vehicle,
A read processing unit (42) that reads out map data for an area determined based on the current position determined by the position determination unit from the map storage unit, and
Based on the map data reading unit has read, the control map creation unit for creating a control map data information amount is often (35) with respect to the map data (43),
It is a map data output device including an output unit (44) that outputs control map data to a vehicle control device that controls the behavior of the vehicle.
車両制御装置へ出力する制御用地図データは地図記憶部に記憶されているのではなく、地図記憶部に記憶されている地図データに対して情報量が多くされたデータである。換言すれば、地図記憶部に記憶されている地図データは、制御用地図データよりも情報が少ないデータである。したがって、制御用地図データを地図記憶部に記憶しておき、その制御用地図データを読み出すよりも、読み出し速度を速くすることができ、また、地図データを記憶するために必要な記憶容量も少なくできる。 Control map data to be outputted to the vehicle control device rather than being stored in the map storage unit, a data number information amount with respect to the map data stored in the map storage unit. In other words, the map data stored in the map storage unit is data with less information than the control map data. Therefore, the reading speed can be increased as compared with storing the control map data in the map storage unit and reading the control map data, and the storage capacity required for storing the map data is small. can.
